I Just Got Finished Installing My Solar Thermal System, Its About 3pm and The Sun Has Been Shining All Day. Should I Begin Commissioning The System With Heat Transfer Fluid?

I Just Got Finished Installing My Solar Thermal System, Its About 3pm and The Sun Has Been Shining All Day.  Should I Begin Commissioning The System With Heat Transfer Fluid? NO!!!  This is dangerous.  If your collectors have been sitting in the sun all day they have been heating up.  As soon as you introduce the Heat Transfer Fluid in...

What Is The Difference Between Flat Plates And Evacuated Tube Collectors?

What is the difference between Flat Plates and Evacuated Tube Collectors? While both types of collectors capture the suns energy and convert it to hot water each have there own advantages. Evacuated Tube Collectors are best used in northern climates where freezing can occur and can be utilized in areas where temperatures drop down to -60°F. Evacuated Tubes are are...

Can I Mount Solar Thermal Collectors On A Flat Roof Without Roof Penetrations?

Can I Mount Solar Thermal Collectors On A Flat Roof Without Roof Penetrations? Yes you can. Collectors can be attached to our ballast system, which uses the weight of standard patio blocks to hold the collectors in place. Wind load calculations must be done by an engineer to conform to local building codes. With the proper weight attached, collectors will...

What is the best angle to position my collectors?

This answer depends on what you are trying to accomplish. For simple Domestic Hot Water systems you should try and position you collectors at the same angle as your latitude. For systems that are tied into the home heating system, as in a combisystem, you should position you collectors 15 degrees higher than your latitude. For summertime use only...

What is more important, postioning the collectors for maximum aesthetic appeal or maximum solar gain?

Do you want to make this system perform to its highest ability or should it look nice and fit the architecture of the house? We have all seen those albatrosses on the roof that are cantilevered at a compound angle to get a few extra BTU's at the cost of aesthetic appeal. Here are some guidelines to consider when deciding what is most...

Is it possible to melt snow off of my collectors?

Yes it is. Depending on your type of collector, you can program your controller to manually activate the circulator which will bring heat from your storage vessel and into the collectors, which will radiate that heat back out thus melting the snow. This method only works for FLAT PLATES however and will usually take as much energy as it...

How do I decide between Flat plate and Evacuated tube?

This will be a debate well in to the future. For an more in-depth review please watch this Click here to watch this 1/2 hour webinar. Your decision should be based primarily on the following considerations: 1- Temperature demand- What is you existing application? EVT's will outperform FP's at higher temp load. 2- Climate location- In a general sense, flat plates...

How do I attach solar panels to my shingle roof without causing leaks?

Our ConnectMaxx roof hooks are designed for any roof. We suggest that each be attached directly into a rafter using two Simpson Strong-Drive screws. Roof caulk can be used to seal these penetrations. (One installer we know used butyl rubber.) Our concave X-mount flashing then fits securely over the roof hook and under the shingles for a weatherproof connection....
